The Radiological/Nuclear
WMD Incident Exercise Site (T-1):
WMD Incident Exercise Site (T-1):
T-1: The Nevada National Security Site's (NNSS) Unique Training Area is like no other training grounds in the United States.

Four atmospheric nuclear tower tests occurred at this location of the NNSS: EASY, on May 7, 1952; SIMON, on April 25, 1953; APPLE-2, on May 5, 1955; and GALILEO, on September 2, 1957. These tests left what are now low amounts of radioactive material in the surrounding soil, providing a realistic and safe training area today. First responders prepare for radiological or nuclear WMD incidents, such as Improvised Nuclear Devices (INDs), Radiological Dispersal Devices (RDDs or “dirty bombs”), and Radiation Exposure Devices (REDs). Other first responder training providers must simulate the radiological threat; at T-1, the soil emits elevated levels of radiation, yet poses minimal risk to trainees. Additional sealed radioactive sources can also be placed in exercise areas to create higher levels of radiation, based upon the training scenarios.
CTOS - Center for Rad/Nuc Training at the Nevada National Security Site (NNSS) Program at the NNSS develops and delivers the training for emergency First Responders.

This training prepares the responders to take immediate, decisive action to prevent or mitigate terrorist use of radiological or nuclear WMDs, such as Improvised Nuclear Devices (INDs) and Radiological Dispersal Devices (RDDs or "dirty bombs").
Training courses and exercises conducted at the NNSS, municipality-hosted locations, and online, provide state and local first responders with the tools they need to protect their communities from these threats. With FEMA/NPD concurrence, CTOS coordinates the development and delivery of preventive radiological/nuclear detection and interdiction training with the Domestic Nuclear Detection Office (DNDO), the DHS entity charged with this responsibility.
